Note:
Zero speed keeping in zero servo: Setting P93.02=2 makes the motor locked at the positioning
function in stop state. This means even if the motor is subjected to external forces, the VFD keeps the
motor unmoved and the load stopped at the position where it stops.
Slow lowering after zero servo zero speed is kept: Setting P93.02=3 makes the VFD enter the zero
speed keeping mode, of which the hold time is set through P93.38. When the hold time is reached,
the slow lowering is automatically used.
